This is a subset from a larger dataset from Home Math Environment project (downloaded here: https://ldbase.org/datasets/28729a95-d898-4271-b16e-dc67be8d8689) In the project, 339 parents of children aged 3 through 8 answered a questionnaire about their attitudes towards their children math education and their in-home math environment.

Data dictionary:

The following information could be visualized:

1. Does parent’s IQ predicts their opinion on how much parents responsible for kids education? Does the number of kids in family moderate this association?
